X-Defenders

Polaris and Havok warrant joint attention as Defenders for a Day. After all, both heroes had been on-again, off-again members of the X-Men and remained overshadowed by related characters.

Although her mutant green hair made Lorna Dane visually distinct, Lorna's magnetic powers intrinsically linked her to the X-Men's earliest foe, Magneto. As a result, Lorna received the monicker "Magneto's daughter" well before she adopted the heroic name Polaris. Similarly, by the time Alex Summers became Havok, his older brother, Cyclops, already held the mantle of field leader of the X-Men.

Joining the Defenders, even for a day, presented Polaris and Havok with an opportunity to continue their crimefighting careers without comparison to other mutants. To this point, the two heroes did not even interact with one another directly during their appearances in Defenders #62-65, prompting others to respond to them individually and not as a pair.

On the topic of individuality, #62 spelled Havok like the word havoc (ending in c). This was not a lasting change, however, as #63 returned to the established spelling of his codename (ending in k).

Lorna Dane appeared on the cover X-Men #50, with interior text hailing her as the daughter of Magneto. X-Men #97 pitted Cyclops against Havok in a story titled "My Brother, My Enemy!"
